Problem 2 (similar, but not identical to book problem book 4.6): Suppose that Alice's RSA public key is (Ne) = (33,3) and her private key is d=7. 1) If Bob encrypts the message M a) what is the ciphertext C? 17 using Alice's public key b) Show that Alice can decrypt C to obtain M 2) Let S be the result when Alice digitally signs the message M = 23. a) What is S? b) If Bob receives M and S, show how Bob verifies the signature
